The Lowdown
Alright, Rusty here, let’s talk about what’s heading our way.
We’ve got a solid run of surf building at Lakey Pipe, starting Sunday the 30th of August and running right through to mid-September. The water is sitting at 80.1°, which is pretty much bang on average for this time of year, so no surprises there.
Sunday morning kicks things off with a clean 4.9ft SW swell, period around 13 seconds, and a light cross-off breeze from the SE. Combined energy is moderate at 933 – not massive, but enough to get you moving. It’s a reef break, exposed to the SW, and the swell direction is right on the money. It’s consistent, so you’ll get plenty of waves. Afternoon holds similar, with energy climbing to 1016, and conditions staying clean.
Monday 31st sees the period jump to 19 seconds in the morning – that’s serious groundswell. Swell height is 3.9ft, but with that long period, the waves will have real shape and power. Energy jumps to 1465. The cross-off wind keeps it clean. This is a standout for me: the combination of that long-period SW groundswell and clean conditions makes for some proper, well-shaped waves at this reef. Afternoon gets a little bigger at 4.9ft and 18 seconds, energy at 1660.
Tuesday 1st September pushes up to 6.9ft in the morning, still clean, with a moderate breeze. Energy is now 2794 – that’s moderate but punching well above its weight. Afternoon shifts to 5.9ft from the SSW, still clean. The swell is getting serious, but the period drops a little to 16 seconds. This is expert territory now, as it’s getting solid.
Wednesday 2nd holds at 6.9ft, clean, with energy around 2575. The breeze is up a bit but still cross-off, so the face stays clean. Thursday 3rd drops slightly to 5.9ft in the morning, energy 1540, and by afternoon it’s 5.2ft. Still clean, still good.
Friday 4th sees a bit of a lull – 4.3ft in the morning, energy down to 748, but the afternoon picks up to 4.6ft and 808 energy. Still clean, but the wave size is smaller.
Saturday 5th brings a bit of cloud cover, but the swell picks back up to 5.2ft, period 13 seconds, energy 913. The wind is light, so it’s glassy. Afternoon jumps to 4.9ft, energy 1255, and the swell direction shifts slightly to the SSW. Clean again.
Sunday 6th is a big one. Morning has 5.6ft, 14 seconds, energy 2125. Afternoon hits 7.5ft, 17 seconds, energy 2815, but the wind swings to a cross-shore from the S, so there’s a little chop on the face. Still, that’s a lot of swell and a very long period.
Monday 7th stays clean in the morning, 6.9ft, 14 seconds, energy 1922. Afternoon goes cross-shore again, but the swell holds. Tuesday 8th drops to 5.6ft in the morning, then 5.9ft in the afternoon with a 16-second period and energy 2436. It’s still cross-shore, so a little bumpy.
Wednesday 9th is the biggest of this run so far: 7.9ft in the morning, 16 seconds, energy 2936. Afternoon is 7.2ft, energy 2500. Still cross-shore, so expect some texture on the wave.
Thursday 10th cleans up again – 6.2ft, 16 seconds, energy 2013, with a light cross-off. Afternoon is 5.9ft, 15 seconds, energy 1688. Clean again.
Friday 11th is a standout long-range prospect. Morning has 6.9ft, 20 seconds, energy 4431. Afternoon goes to 8.2ft, 19 seconds, energy 5161 – that’s strong wave energy. Both sessions are clean with cross-off winds. That 20-second period is very long, so the sets will be widely spaced but powerful. This reef handles that well.
Saturday 12th gets too big for the break in the morning – 9.8ft, 17 seconds, energy 4826. That’s expert-only, and even then, it might be pushing the limits. Afternoon drops to 8.2ft, energy 3877, still clean, and that’s more manageable for experienced surfers.
Sunday 13th is a beauty: 7.2ft, 16 seconds, energy 3193, clean. Afternoon is 6.9ft, 16 seconds, energy 3887, with a light breeze. Both sessions are clean, and the swell is solid but not out of control.
Monday 14th sees another 9.8ft morning, too big for the break. Afternoon drops to 8.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
